[FEAT] Include a new globallink install strategy

[TheBrenny]

A globallink install strategy should be included and would work similar to how the linked strategy works now. However, instead of the packages being saved in ./node_modules/.store, they would be saved in /path/to/npm/global/node_modules/.store.

This will allow developers to reduce the amount of package duplication across projects.

This will also create an update to the clean-install command where the packages (and exact dependencies) for a project are deleted from the global store and re-installed.
